9 Claims. {(C]. 255*51) This invention relates to a ventilating hole-drilling machine supporting frame, and has for one of its objects the production of a simple andefiicient means for supporting a machine for drilling holes under windows in existing buildings to provide for the insertion therein of fresh air intakes for air-conditioningequipment, and the like.

A further object of this invention is the production of a simple and efiicient frame for supportinga-drillinteriorly of a wall of a building to facilitate the drillingo'fa hole under a window of an existing building, theframebeing so constructed as to extend through a window and to engage both the inner and outer faces of the wall forthe purpose of efficiently holding and-guiding a drill-during operation.

Other advantages and objects of the presentinvention will appear throughout the following specification and claims.

By referring to the drawings in detail, it will be seen that 10 designates the base rails of the carriage track which is adapted to rest upon a suitable support S, shown in dotted line in Figure 1. Track rails 11 are connected at their forward ends to the base rails it by means of hinges 12. The base rails are braced by transverse braces 13 and the track rails 11 are braced by the transverse braces 14. The track rails 11 are held at a proper angle relative to the base rails 10 by suitable upstanding braces, such as the brace 15 shown in Figure 1, preferably one 2,730,334 Patented Jan. 10, 1956 for each track rail located near the rear 'end of each track rail.

Ahanger frame 16 is adapted to engage the wall of a building, as shown, and this hanger frame 16 comprises a pair of outer vertical parallel angle bars 17 and 18 and iapair-of inner vertical parallel angle bars 19 and 20. The outer vertical bars 17 and 18 are-transversely braced in :spaced relation by means of the angle bar 21. The inner vertical bars 19 and 211 are transversely braced in spaced relation by means of the angle bar22.

.A connecting rod 23 is fixed at one end 24 to the upper end of the angle bar 17 and its opposite threaded end carries a'lockwing nut 25 which engages the inner face of the angle bar 19. The threaded end of the rod 23 passes through a sleeve :26 at the upper end of the angle bar 19, and a wing nut 27 is threaded upon the outer extremityof thearod '23 to secure the rod 23 to the outer face of the sleeve 26. A 'rod 23 is similarly secured at its inner end to the angle bar 18 and its outer end extends through the sleeve 26 -of the angle bar 2%, and is similarly anchored to the sleeve 26 in the same manner as described relative to the sleeve 26. In this manner the upper ends of the angle bars v1'7 and 13 are held in proper spaced relation with respect to the upper ends of the bars '19 and-2t Rods 23 and 29 are anchored to the transverse bar at their outer ends, and the forward threaded ends ex tend through the sleeves -30 and 31, which are carried by the respective bars 19 and 20. Wing nuts 32and33 anchor the forward ends of the rods 23 and 29 to the respective bars '19 and 2d. .The bar 17 carries a clamping block 34 near its lower end and the bar 18 carries a clamping block 35 near its lowerend for clamping engagement against the outer face of the wall W, shown in-dotted lines'below the window W. The bar 19 carries a clamping block 36 near-its lower end and the bar 20 carries a clamping block 37 near its lower end. These blocks 36 and 37 engage the frontface of the wall W. In this manner, the'hanger frame 16 is clamped against the front .andirear faces of the wall W, while .the rods 23, .29, 23 and23 extend through the window W, to connect the upper .ends' of the bars'17 and 18 to the upper ends of the bars 18 and 19.

Thetrackirails 11 are held at a selected angle by the bracing means -15, and thelink 38 whichis anchored at one end in the-socket39 carried by the lower end of the vertical angle bars 19 and 20, as shown in detail in Figure '5. The opposite .end IOfrI'hC-lillk 38 is selectively and removably fitted in the sockets 40 formed preferably in the sides of both rails 11. A protector plate 41 having apertures 42 registering with the sockets 40, is carried by both rails in which the sockets 40 are formed. The angle of the track rails 11 may be changed to accommodate the work which is being performed, and to support the drill D, hereinafter described, at a selected angle which may range from horizontal to a pitch of more than thirty degrees.

A carriage 43 preferably formed of channel-type construction, carries supporting wheels or rollers 44 which wheels or rollers 44 travel upon the track rails 11, as shown in Figures 1 and 7. Drill supporting plates 45 and 46 are carried by the carriage 43, and are provided with a plurality of apertures 47 and 48, respectively, to facilitate securing the drill D in a selected position between the plates 45 and 46.

The present device is designed for use in conjunction with a large carbide or diamond-tipped masonry core drill of a conventional type which is sold throughout the country. The drill is adapted to drill holes three to six inches in diameter, and the present apparatus is adapted to maintain a constant pressure upon the bit to provide the desired cutting action. This structure furnishes proper mechanical assistance to accomplish the desired results. The rear of the drill ;D engages the bearing block 49, and this block is carried by the transversely extending drill feeding bar 50 through which the anchoring bars 51 and 52 extend. These anchoring bars 51 and 52 are hooked or anchored at their inner ends in selected vertically aligned apertures 53 formed in the vertical bars 19 and 20, and the outer ends pass through the drill feeding bar 50. Wing nuts 54 and 55 are carried by the bars 51 and 52 and engage the drill feeding bar 50 to facilitate feeding the drill D toward the work as these wing nuts are adjusted.

It will be noted that when the track rails 11 are at an angle, or are on an incline, the carriage 43 will feed the drill toward the work by gravity and pressure will be applied upon the bearing block 49 and to the drill as the nuts 54 and 55 are threaded toward the work, to move the bar 50 downwardly toward the work.

As shown in Figures 10 to 12, inclusive, the anchoring bar 50 may be shaped from metal or other material and is provided with a central longitudinal rib portion 56 which is longitudinally slotted, as shown at 57 in Figures 10 and 12. A journal portion is provided at each end of the bar 50, such as the journal portion 58 through which the bars, such as the bar 51*, extend. A bearing block 49 is carried by the anchoring bar 50*. A wing nut 54 is carried by the bars 51 and a similar wing nut is carried by the other bar at the opposite end of the anchoring bar 50 in a similar manner to the nuts 54 and 55, shown in Figure 2. These, however, are only structural details which may be varied within the function of the invention.

It should be understood that certain detail changes in the structure and arrangement of parts may be employed without departing from the function of the invention.
